An official of a large national union claims that the fraction of women in the union is not significantly different from one-half. Using the critical value approach and the sample information reported below, carry out a test of this statement. Let a = 0.05. Ho sample size 400 H₂: women men 162 State the null and alternative hypotheses. (Enter != for as needed.) 238 Find the value of the test statistic. Determine the critical value(s) for this test. (Round your answer(s) to two decimal places. If the test is one-tailed, enter NONE for the unused tail.) test statistic S test statistic 2 State your conclusion. O Do not reject Ho. There is insufficient evidence to conclude that the fraction of women in the union is significantly different from one-half. O Reject Ho. There is sufficient evidence to conclude that the fraction of women in the union is significantly different from one-half. O Reject Ho. There is insufficient evidence to conclude that the fraction of women in the union is significantly different from one-half. O Do not reject Ho. There is sufficient evidence to conclude that the fraction of women in the union is significantly different from one-half.
